[Solved] Get displayrange of chartseries

[Michael]

Hi,
I enabled zooming in a RadCartesianChart and wanted to get the current visible range of the displayed x series.
e.g my series contains values from 1 - 100 and i zoomed in that only 20-40 are displayed, I wanted to get this information somehow. It is needed to update some other control (e.g a grid).
Any hints how I can get this information?
many thx, Michi

Hello Michael,

Thank you for your interest in our suite.

I can suggest you to track the changes in RadCartesianChart.ScrollOffset / Zoom properties. In the following scenario the RadCartesianChart.Zoom property will be (5,1) and the ScrollOffset will be (-1,0). If ScrollOffset changes to (-2,0)  - then 40-60 values will be displayed and so on.

Also, if you are using DateTimeContinuousAxis or LinearAxis as your horizontal axis, you can get the actual visible range for the axis from the DateTimeContinuousAxis.ActualRange (LinearAxis.ActualRange) read-only property.

I hope this helps. Let me know if I can assist you any further.
